Collecting posture information to evaluate therapy
First Claim
1. A method comprising:
- monitoring a plurality of signals, each of the signals generated by a respective one of a plurality of sensors as a function of posture of a patient;
identifying a plurality of posture events based on the signals;
associating each of the posture events with a therapy parameter set that was used by a medical device to deliver a therapy to the patient when the posture event was identified; and
for each of the plurality of therapy parameter sets, determining a value of a posture metric based on the posture events associated with the therapy parameter set, the value of the posture metric indicating an efficacy of the therapy parameter set.

Abstract
A medical device delivers a therapy to a patient. The medical device may identify posture events, e.g., periodically determine a posture of the patient and/or identify posture transitions by the patient, and associate each determined posture event with a current therapy parameter set. A value of at least one posture metric is determined for each of a plurality of therapy parameter sets based on the posture events associated with that therapy parameter set. A list of the therapy parameter sets is presented to a user, such as a clinician, for evaluation of the relative efficacy of the therapy parameter sets. The list may be ordered according to the one or more posture metric values to aid in evaluation of the therapy parameter sets. Where values are determined for a plurality of posture metrics, the list may be ordered according to the one of the posture metrics selected by the user.
